A little puzzle, guys...
This is the first spectrum I captured tonight. I plugged NGC3372 into the scope and it slewed straight to this. I took one look at it and immediately thought I had Eta Carinae. But do I?
The continuum is a very different shape to the raw etas I've captured before - this one is much bluer / hotter... and there is a strong double line bluewards of Hb.
Can anyone verify if Eta Carinae is changing, or have I picked up another star?
Al.
